The KAL-L airflow performs rapid detection of flow rate changes in non-hazardous gases. It employs two RTD's, one to sense flow and the other to detect ambient temperature, and compensates for thermal changes in its surroundings. Features include a measuring range of 1 to 20 m/s air, maximum pressure of 120 PSIG, maximum temperature of 250°F, and a switching accuracy of ±10% of reading. Typical applications include air conditioning systems, ventilation systems, and conveying plants. For a datasheet, go to http://koboldusa.com/sites/default/files/product_files/KAL-L_datasheet.pdf
